Richard Burton first gifted a Bulgari emerald brooch and teardrop earrings and later bought the Krupp Diamond — a 33.19‑carat center stone with tapered baguette sides set in platinum. The gem, once owned by Vera Krupp and auctioned after her 1967 death, was purchased by Burton in 1968 for $307,000 and sold at auction after Taylor's death for $8.8 million.
By current estimates Grace Kelly's emerald‑cut leads at $38.8 million, Taylor's Krupp Diamond follows at $8.8 million, and Hepburn's three‑band set is the least valuable. After Grace's 1982 death her Cartier ring passed to the House of Grimaldi and was shown at Cartier’s Fifth Avenue mansion in 2016.
